The Ford Nucleon was a nuclear-powered concept car developed by Ford Motor Company in 1958. The car did not have an internal-combustion engine, rather, it was powered by a small nuclear reactor in the trunk of the car. The vehicle featured a power capsule suspended between twin booms at the rear. The capsule, which would contain radioactive core for motive power, was designed to be easily interchangeable, according to performance needs and the distances to be traveled. Source - Wikipedia.
